rework config.ini searching
By default the config.ini should be searched in the same directory of the binary. If it's not found maybe could be in the parent of the binary, inside `Resources/` (we are on macos). Added also some logging. Use `go-paths-helper` to ease things.

GNU GENERAL PUBLIC LICENSE
12+
Version 2, June 1991
13+
14+
Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
15+
51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
16+
Everyone is permitted to copy and distribute verbatim copies
17+
of this license document, but changing it is not allowed.
18+
19+
Preamble
20+
21+
The licenses for most software are designed to take away your
22+
freedom to share and change it. By contrast, the GNU General Public
23+
License is intended to guarantee your freedom to share and change free
24+
software--to make sure the software is free for all its users. This
25+
General Public License applies to most of the Free Software
26+
Foundation's software and to any other program whose authors commit to
27+
using it. (Some other Free Software Foundation software is covered by
28+
the GNU Lesser General Public License instead.) You can apply it to
29+
your programs, too.
30+
31+
When we speak of free software, we are referring to freedom, not
32+
price. Our General Public Licenses are designed to make sure that you
33+
have the freedom to distribute copies of free software (and charge for
34+
this service if you wish), that you receive source code or can get it
35+
if you want it, that you can change the software or use pieces of it
36+
in new free programs; and that you know you can do these things.
37+
38+
To protect your rights, we need to make restrictions that forbid
39+
anyone to deny you these rights or to ask you to surrender the rights.
40+
These restrictions translate to certain responsibilities for you if you
41+
distribute copies of the software, or if you modify it.
42+
43+
For example, if you distribute copies of such a program, whether
44+
gratis or for a fee, you must give the recipients all the rights that
45+
you have. You must make sure that they, too, receive or can get the
46+
source code. And you must show them these terms so they know their
47+
rights.
48+
49+
We protect your rights with two steps: (1) copyright the software, and
50+
(2) offer you this license which gives you legal permission to copy,
51+
distribute and/or modify the software.
52+
53+
Also, for each author's protection and ours, we want to make certain
54+
that everyone understands that there is no warranty for this free
55+
software. If the software is modified by someone else and passed on, we
56+
want its recipients to know that what they have is not the original, so
57+
that any problems introduced by others will not reflect on the original
58+
authors' reputations.
59+
60+
Finally, any free program is threatened constantly by software
61+
patents. We wish to avoid the danger that redistributors of a free
62+
program will individually obtain patent licenses, in effect making the
63+
program proprietary. To prevent this, we have made it clear that any
64+
patent must be licensed for everyone's free use or not licensed at all.
65+
66+
The precise terms and conditions for copying, distribution and
67+
modification follow.
68+
69+
GNU GENERAL PUBLIC LICENSE
70+
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
71+
72+
0. This License applies to any program or other work which contains
73+
a notice placed by the copyright holder saying it may be distributed
74+
under the terms of this General Public License. The "Program", below,
75+
refers to any such program or work, and a "work based on the Program"
76+
means either the Program or any derivative work under copyright law:
77+
that is to say, a work containing the Program or a portion of it,
78+
either verbatim or with modifications and/or translated into another
79+
language. (Hereinafter, translation is included without limitation in
80+
the term "modification".) Each licensee is addressed as "you".
81+
82+
Activities other than copying, distribution and modification are not
83+
covered by this License; they are outside its scope. The act of
84+
running the Program is not restricted, and the output from the Program
85+
is covered only if its contents constitute a work based on the
86+
Program (independent of having been made by running the Program).
87+
Whether that is true depends on what the Program does.
88+
89+
1. You may copy and distribute verbatim copies of the Program's
90+
source code as you receive it, in any medium, provided that you
91+
conspicuously and appropriately publish on each copy an appropriate
92+
copyright notice and disclaimer of warranty; keep intact all the
93+
notices that refer to this License and to the absence of any warranty;
94+
and give any other recipients of the Program a copy of this License
95+
along with the Program.
96+
97+
You may charge a fee for the physical act of transferring a copy, and
98+
you may at your option offer warranty protection in exchange for a fee.
99+
100+
2. You may modify your copy or copies of the Program or any portion
101+
of it, thus forming a work based on the Program, and copy and
102+
distribute such modifications or work under the terms of Section 1
103+
above, provided that you also meet all of these conditions:
104+
105+
a) You must cause the modified files to carry prominent notices
106+
stating that you changed the files and the date of any change.
107+
108+
b) You must cause any work that you distribute or publish, that in
109+
whole or in part contains or is derived from the Program or any
110+
part thereof, to be licensed as a whole at no charge to all third
111+
parties under the terms of this License.
112+
113+
c) If the modified program normally reads commands interactively
114+
when run, you must cause it, when started running for such
115+
interactive use in the most ordinary way, to print or display an
116+
announcement including an appropriate copyright notice and a
117+
notice that there is no warranty (or else, saying that you provide
118+
a warranty) and that users may redistribute the program under
119+
these conditions, and telling the user how to view a copy of this
120+
License. (Exception: if the Program itself is interactive but
121+
does not normally print such an announcement, your work based on
122+
the Program is not required to print an announcement.)
123+
124+
These requirements apply to the modified work as a whole. If
125+
identifiable sections of that work are not derived from the Program,
126+
and can be reasonably considered independent and separate works in
127+
themselves, then this License, and its terms, do not apply to those
128+
sections when you distribute them as separate works. But when you
129+
distribute the same sections as part of a whole which is a work based
130+
on the Program, the distribution of the whole must be on the terms of
131+
this License, whose permissions for other licensees extend to the
132+
entire whole, and thus to each and every part regardless of who wrote it.
133+
134+
Thus, it is not the intent of this section to claim rights or contest
135+
your rights to work written entirely by you; rather, the intent is to
136+
exercise the right to control the distribution of derivative or
137+
collective works based on the Program.
138+
139+
In addition, mere aggregation of another work not based on the Program
140+
with the Program (or with a work based on the Program) on a volume of
141+
a storage or distribution medium does not bring the other work under
142+
the scope of this License.
143+
144+
3. You may copy and distribute the Program (or a work based on it,
145+
under Section 2) in object code or executable form under the terms of
146+
Sections 1 and 2 above provided that you also do one of the following:
147+
148+
a) Accompany it with the complete corresponding machine-readable
149+
source code, which must be distributed under the terms of Sections
150+
1 and 2 above on a medium customarily used for software interchange; or,
151+
152+
b) Accompany it with a written offer, valid for at least three
153+
years, to give any third party, for a charge no more than your
154+
cost of physically performing source distribution, a complete
155+
machine-readable copy of the corresponding source code, to be
156+
distributed under the terms of Sections 1 and 2 above on a medium
157+
customarily used for software interchange; or,
158+
159+
c) Accompany it with the information you received as to the offer
160+
to distribute corresponding source code. (This alternative is
161+
allowed only for noncommercial distribution and only if you
162+
received the program in object code or executable form with such
163+
an offer, in accord with Subsection b above.)
164+
165+
The source code for a work means the preferred form of the work for
166+
making modifications to it. For an executable work, complete source
167+
code means all the source code for all modules it contains, plus any
168+
associated interface definition files, plus the scripts used to
169+
control compilation and installation of the executable. However, as a
170+
special exception, the source code distributed need not include
171+
anything that is normally distributed (in either source or binary
172+
form) with the major components (compiler, kernel, and so on) of the
173+
operating system on which the executable runs, unless that component
174+
itself accompanies the executable.
175+
176+
If distribution of executable or object code is made by offering
177+
access to copy from a designated place, then offering equivalent
178+
access to copy the source code from the same place counts as
179+
distribution of the source code, even though third parties are not
180+
compelled to copy the source along with the object code.
181+
182+
4. You may not copy, modify, sublicense, or distribute the Program
183+
except as expressly provided under this License. Any attempt
184+
otherwise to copy, modify, sublicense or distribute the Program is
185+
void, and will automatically terminate your rights under this License.
186+
However, parties who have received copies, or rights, from you under
187+
this License will not have their licenses terminated so long as such
188+
parties remain in full compliance.
189+
190+
5. You are not required to accept this License, since you have not
191+
signed it. However, nothing else grants you permission to modify or
192+
distribute the Program or its derivative works. These actions are
193+
prohibited by law if you do not accept this License. Therefore, by
194+
modifying or distributing the Program (or any work based on the
195+
Program), you indicate your acceptance of this License to do so, and
196+
all its terms and conditions for copying, distributing or modifying
197+
the Program or works based on it.
198+
199+
6. Each time you redistribute the Program (or any work based on the
200+
Program), the recipient automatically receives a license from the
201+
original licensor to copy, distribute or modify the Program subject to
202+
these terms and conditions. You may not impose any further
203+
restrictions on the recipients' exercise of the rights granted herein.
204+
You are not responsible for enforcing compliance by third parties to
205+
this License.
206+
207+
7. If, as a consequence of a court judgment or allegation of patent
208+
infringement or for any other reason (not limited to patent issues),
209+
conditions are imposed on you (whether by court order, agreement or
210+
otherwise) that contradict the conditions of this License, they do not
211+
excuse you from the conditions of this License. If you cannot
212+
distribute so as to satisfy simultaneously your obligations under this
213+
License and any other pertinent obligations, then as a consequence you
214+
may not distribute the Program at all. For example, if a patent
215+
license would not permit royalty-free redistribution of the Program by
216+
all those who receive copies directly or indirectly through you, then
217+
the only way you could satisfy both it and this License would be to
218+
refrain entirely from distribution of the Program.
219+
220+
If any portion of this section is held invalid or unenforceable under
221+
any particular circumstance, the balance of the section is intended to
222+
apply and the section as a whole is intended to apply in other
223+
circumstances.
224+
225+
It is not the purpose of this section to induce you to infringe any
226+
patents or other property right claims or to contest validity of any
227+
such claims; this section has the sole purpose of protecting the
228+
integrity of the free software distribution system, which is
229+
implemented by public license practices. Many people have made
230+
generous contributions to the wide range of software distributed
231+
through that system in reliance on consistent application of that
232+
system; it is up to the author/donor to decide if he or she is willing
233+
to distribute software through any other system and a licensee cannot
234+
impose that choice.
235+
236+
This section is intended to make thoroughly clear what is believed to
237+
be a consequence of the rest of this License.
238+
239+
8. If the distribution and/or use of the Program is restricted in
240+
certain countries either by patents or by copyrighted interfaces, the
241+
original copyright holder who places the Program under this License
242+
may add an explicit geographical distribution limitation excluding
243+
those countries, so that distribution is permitted only in or among
244+
countries not thus excluded. In such case, this License incorporates
245+
the limitation as if written in the body of this License.
246+
247+
9. The Free Software Foundation may publish revised and/or new versions
248+
of the General Public License from time to time. Such new versions will
249+
be similar in spirit to the present version, but may differ in detail to
250+
address new problems or concerns.
251+
252+
Each version is given a distinguishing version number. If the Program
253+
specifies a version number of this License which applies to it and "any
254+
later version", you have the option of following the terms and conditions
255+
either of that version or of any later version published by the Free
256+
Software Foundation. If the Program does not specify a version number of
257+
this License, you may choose any version ever published by the Free Software
258+
Foundation.
259+
260+
10. If you wish to incorporate parts of the Program into other free
261+
programs whose distribution conditions are different, write to the author
262+
to ask for permission. For software which is copyrighted by the Free
263+
Software Foundation, write to the Free Software Foundation; we sometimes
264+
make exceptions for this. Our decision will be guided by the two goals
265+
of preserving the free status of all derivatives of our free software and
266+
of promoting the sharing and reuse of software generally.
267+
268+
NO WARRANTY
269+
270+
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
271+
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
272+
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
273+
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
274+
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
275+
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
276+
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
277+
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
278+
REPAIR OR CORRECTION.
279+
280+
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
281+
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
282+
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
283+
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
284+
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
285+
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
286+
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
287+
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
288+
POSSIBILITY OF SUCH DAMAGES.
289+
290+
END OF TERMS AND CONDITIONS
291+
292+
How to Apply These Terms to Your New Programs
293+
294+
If you develop a new program, and you want it to be of the greatest
295+
possible use to the public, the best way to achieve this is to make it
296+
free software which everyone can redistribute and change under these terms.
297+
298+
To do so, attach the following notices to the program. It is safest
299+
to attach them to the start of each source file to most effectively
300+
convey the exclusion of warranty; and each file should have at least
301+
the "copyright" line and a pointer to where the full notice is found.
302+
303+
<one line to give the program's name and a brief idea of what it does.>
304+
Copyright (C) <year> <name of author>
305+
306+
This program is free software; you can redistribute it and/or modify
307+
it under the terms of the GNU General Public License as published by
308+
the Free Software Foundation; either version 2 of the License, or
309+
(at your option) any later version.
310+
311+
This program is distributed in the hope that it will be useful,
312+
but WITHOUT ANY WARRANTY; without even the implied warranty of
313+
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
314+
GNU General Public License for more details.
315+
316+
You should have received a copy of the GNU General Public License along
317+
with this program; if not, write to the Free Software Foundation, Inc.,
318+
51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
319+
320+
Also add information on how to contact you by electronic and paper mail.
321+
322+
If the program is interactive, make it output a short notice like this
323+
when it starts in an interactive mode:
324+
325+
Gnomovision version 69, Copyright (C) year name of author
326+
Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
327+
This is free software, and you are welcome to redistribute it
328+
under certain conditions; type `show c' for details.
329+
330+
The hypothetical commands `show w' and `show c' should show the appropriate
331+
parts of the General Public License. Of course, the commands you use may
332+
be called something other than `show w' and `show c'; they could even be
333+
mouse-clicks or menu items--whatever suits your program.
334+
335+
You should also get your employer (if you work as a programmer) or your
336+
school, if any, to sign a "copyright disclaimer" for the program, if
337+
necessary. Here is a sample; alter the names:
338+
339+
Yoyodyne, Inc., hereby disclaims all copyright interest in the program
340+
`Gnomovision' (which makes passes at compilers) written by James Hacker.

343+
Ty Coon, President of Vice
344+
345+
This General Public License does not permit incorporating your program into
346+
proprietary programs. If your program is a subroutine library, you may
347+
consider it more useful to permit linking proprietary applications with the
348+
library. If this is what you want to do, use the GNU Lesser General
349+
Public License instead of this License.
